发布表格问题后如何解决空白页？

我想向视图发送基本表格。我创建了所需的所有内容，但是当我提交帖子时，它不会发送返回空白页。这是我的表单和应用程序：报告是与表单相同的页面，因为我想返回同一页面。我需要Year_one和Year_two的值。

<form  method="post" action="{% url 'app:reports' %}">
    {% csrf_token %}
    <label for="year_one">Select year 1:</label>
    <select id="year_one" name="year_one">
        {% for case in query_trend %}
            <option value="{{case.date_created__year}}"  >{{case.date_created__year}}</option>
        {% endfor %}
    </select>

    <label for="year_two">Select year 2:</label>
    <select id="year_two" name="year_two">
        {% for case in query_trend %}
            <option value="{{case.date_created__year}}">{{case.date_created__year}}</option>
        {% endfor %}
    </select>
    <button onclick="test()">click</button>
</form>

这是我的观点，

if self.request.method == 'POST':
            year_one = self.request.GET.get('year_one')
            year_two = self.request.GET.get('year_two')
            return HttpResponseRedirect('fdm:outstanding_reports')

在视图中使用这些值该怎么办？

原文

I want to send a basic form to views. I create everything that it need but when I submit the post, it doesn't send a return a blank page.
This is my form and app:reports is the same page with form, because I want to return the same page. I need the values of year_one and year_two.

<form  method="post" action="{% url 'app:reports' %}">
    {% csrf_token %}
    <label for="year_one">Select year 1:</label>
    <select id="year_one" name="year_one">
        {% for case in query_trend %}
            <option value="{{case.date_created__year}}"  >{{case.date_created__year}}</option>
        {% endfor %}
    </select>

    <label for="year_two">Select year 2:</label>
    <select id="year_two" name="year_two">
        {% for case in query_trend %}
            <option value="{{case.date_created__year}}">{{case.date_created__year}}</option>
        {% endfor %}
    </select>
    <button onclick="test()">click</button>
</form>

And this is my view

if self.request.method == 'POST':
            year_one = self.request.GET.get('year_one')
            year_two = self.request.GET.get('year_two')
            return HttpResponseRedirect('fdm:outstanding_reports')

What should I do for using these values in views?

假设您的按钮的test（）方法成功地提交了表单...如果您将请求传递给视图，即，

def reports(request):

您可以参考earl_one_one的张贴值和earth_two的张贴值，为：（

    if request.method == 'POST':
        year_one = request.POST.get('year_one')
        year_two = request.POST.get('year_two')

get是在发送中包含的值时URL，例如？ear_1 = 1975＆amp; year_2 = 1300，帖子是在后台发生的使用小写'.get（）'检索帖子值）

Assuming your button's test() method is successfully submitting the form...If you are passing the request to your view,ie,

def reports(request):

Then you can refer to the posted values of year_one and year_two as:

    if request.method == 'POST':
        year_one = request.POST.get('year_one')
        year_two = request.POST.get('year_two')

(GET is when you send values contained in the URL, eg page?year_1=1975&year_2=1300, POST is when it happens in the background. A form will generally use only one or the other, so you your version probably wasn't getting any values. Confusingly, you also use the lowercase '.get()' to retrieve the POST values)
